I have exagear desktop on a Pi 3b+It seems to work fine - I have used various software in the x86 environment with no problems.However, I wanted to set up some scheduled tasks on the Pi (including one in the x86), so I looked at the Pi help topic on cron at https://www.raspberrypi.org/documentation/linux/usage/cron.md

It suggested installing a gui for cron using:

sudo apt-get install gnome-schedule

When I ran this (seemed to take forever) I got these nasty looking warnings during the installation:

Setting up cron (3.0pl1-127+deb8u1) ...update-rc.d: warning: start and stop actions are no longer supported; falling back to defaultsupdate-rc.d: The service *cron* exists both in host and guest systems.This configuration is not supported; please refer to the user guide for more details.invoke-rc.d: The service *cron* exists both in host and guest systems.This configuration is not supported; please refer to the user guide for more details.

and

Setting up rsyslog (8.4.2-1+deb8u2) ...update-rc.d: The service *rsyslog* exists both in host and guest systems.This configuration is not supported; please refer to the user guide for more details.invoke-rc.d: The service *rsyslog* exists both in host and guest systems.This configuration is not supported; please refer to the user guide for more details.

I'm assuming the references to "host and guest systems" indicates a problem with exagear?
